ABSTRACT 



Feeding trials were conducted at the Salmon -Cultural Laboratory (Entiat, Wash.) during 

 1953 and 1954 using Chinook and blueback salmon as the test animals. 



One excellent diet for Chinook salmon finger lings utilizing arrow -toothed halibut 

 (Atheresthes stomias) as a substitute for a portion of the more expensive meat components was developed 

 during the 1953 feeding trials. 



The 1954 blueback salmon feeding trials were designed to develop virus-free rations. 

 Several diets devoid of salmon viscera, the suspect carrier, were tested and found satisfactory. 



The 1954 chinook experiments were designed to study diets containing 50 percent of dry 

 meals. No satisfactory hig^-meal diet was produced from these trials.
